Regarding penile cancer:
Then there's the real world facts that show otherwise as well:
It is thus categorically not true that circumcision eliminates the risk of penile cancer, although that assertion has been made nonchalantly in a number of papers by Schoen, Wiswell, and Weiss. In fact, the data indicate that only other factors -- among them cigarette smoking,18,27 genital warts, and 30 or more sexual partners -- contribute to the risk of penile carcinoma.27
...
There are many documented cases of penile cancer in circumcised men. To reduce the risk of penile cancer, men are best advised simply to use reasonable hygiene, practice responsible sexual behavior, and to avoid handling tobacco.
The history of the penile cancer myth was published by Fleiss and Hodges in the British Medical Journal30.
...
It is now clear that the major risk factors for both penile cancer and cervical cancer are the use of tobacco,27,33 which spreads carcinogens throughout the body via the bloodstream, and the presence of the human papillomavirus,35 which is communicated through sexual activity.
Abraham Wolbarst's promotional claims that circumcision prevented penile cancer were false and mislead the medical community for decades.30 Circumcision does not prevent penile cancer in men and it does not prevent cervical cancer in the female partner.

Penile cancer is one of the rarest cancers - rarer even than breast cancer in men - and figures for it are hard to come by. Circumcised men get penile cancer at about the same tiny rate as intact men. Studies that seemed to show a correlation had not been corrected for age; penile cancer is a disease of old men, and the old men with cancer in the studies had simply been born at a time when circumcision was less customary than when the younger men without cancer were born. When men of the same ages were compared, the correlation vanished.
